Cat escreve texto com “$” dentro

2

Eu quero gravar informações de configuração em um arquivo específico que tenha cifrões ( $ ) dentro. Isso parece ser um problema.

Veja o que eu fiz:

$ cat >> /etc/nginx/nginx.conf <<EOF
# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user              nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log;
#error_log  /var/log/nginx/error.log  notice;
#error_log  /var/log/nginx/error.log  info;

pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    ## Detect when HTTPS is used
    map $scheme $https {
      default off;
      https on;
    }
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    # Load config files from the /etc/nginx/conf.d directory
    # The default server is in conf.d/default.conf
    include /etc/nginx/conf.d/*.conf;

}
EOF

Como posso resolver isso?

Citar EOF :

$ var=foo
$ cat << EOF
> $var
> EOF
foo
$ cat << 'EOF'
> $var
> EOF
$var

De man bash :

If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded.
